You get the Tiger and the Shade.
Because I like them.
Keep in mind though, they are going to be a bit weaker now. The fact that they have more or less willingly agreed to remain here makes their raw power level dip slightly..
Demons are beings of the outer planes (Like Celestials, Elementals, and Fae) and prolonged separation from their home weakens them slowly. Willingly agreeing to remain on the material plane also reduces their power level.
So the Shade probably can't kill with a touch anymore, and the Tiger won't be able to throw humans around with ease. They'll still be formidable, but not anymore than the players.
